【答案】

【1】E

【2】G

【3】A

【5】F

【解析】

试题分析：本文介绍了几种减少电脑辐射的方法

【1】E本段是关于用绿茶来减少电脑辐射的影响，故E项正确。

【2】G绿茶还有另外的功能就是提高视力，故G项正确

【3】A根据下句The brighter the screen the higher the radiation there will be and vice versa.说明屏幕的亮度也是影响人们视力的原因，那么就要调整屏幕的亮度。故A项正确。

【4】B根据下一句Wash your face soon after using the computer在用完电脑以后要洗脸。那么之前也要采取措施，选项中只有B项是与之有关的。故B下符合上下文。

【5】F根据下句Old computer in general, has one to two times more radiation released than the new one within the same distance.说明旧电脑的辐射较大，那么应该使用新的电脑。故F项正确。

【七选五题型分析】

分析篇章结构，把握全篇文脉是阅读填空题解题的关键，英语的语篇（discourse）通常是由句子和语段（sentence group）构成的，语段是句子和语篇之间的中间层次，句子虽然能够单独地表达相对完整的思想，但是它不能表达多方面的、比较复杂的思想，只有把几个句子结合为较大的言语片段，才能表达一个相对独立的层意，所谓的“积句而成章，积章而成篇。”就是这个道理。

分析文章的层次包含两种形式：一种是分析整篇文章的层次，也就是段落，另一种是分析每一个段落内部的层次，也就是语篇层次。

语篇与段落是有区别的，语段是篇章结构的中间层次，是由句子到篇的一种过渡形式，段落（paragraph）是在某些语体（如记叙文、议论文）中比语段更大的意义单位，较小的段落可以只包括一个语段或一个句子，一般来说，一个段落通常由几个语段构成。构成语段的方式有两种，一是靠句际间意义的结合，如小题4 B根据下一句Wash your face soon after using the computer在用完电脑以后要洗脸。那么之前也要采取措施，选项中只有B项是与之有关的。故B下符合上下文。

二是靠句际间的关联词，逻辑性插入语来连接，在分析语段层次时，可以借助句际间的连接词语作出判断，但最主要的还是要真正体会句际间的意义关系，把握作者的思路，从语序上去发现断续点，理清层次，好文章的层次非常清晰，只有层层入手，才能真正理解文章。如小题3 A根据下句The brighter the screen the higher the radiation there will be and vice versa.说明屏幕的亮度也是影响人们视力的原因，那么就要调整屏幕的亮度。故A项正确。
